    Is there any way to see extern methods like String.ReplaceInternal()?

    Hi Robert,

    I tried both the F12 addin and the single stepping over .Net code technique, but both simply did not work for me.

    I have VS 2013 Ultimate 64, and I have JetBrains ReSharper and DevExpress CodeRush installed in my computer. For the testing I disabled ReSharper and unloaded CodeRush, but to no avail.

    I checked all the required conditions as outlined in the corresponding sites, but, again, it did not work.

    Am I missing something here?

    I would really like to be able to use these features because they seems to be very useful.

    May I have some help here?

    Thanks for your support,

    Eduardo Quintana

    @philippecp:Right now we do not have support for native methods.

    @eduquint:could you use the instructions on the site to send us the information and we can look at what the issue is.

    it would be interesting to see the associated tests as well. especially the tests for the data annotations. would this be a possibility?

    @ronnel: we can definitely keep this in mind as we add code to the site.
